Abstract (en)
[origin: EP2000633A2] A containment system (40) comprises at least one passage obstructer (41) extending from a housing inlet cover (64) through a diffuser passage (67) and into a housing back cover (66). The passage obstructer (41) includes a fastener portion (42), such as a bolt, and an obstructing portion (43) extending from and integral to a shaft (45) of the fastener portion (42). The diameter (49) of the obstructing portion (43) is less than the diameter (50) of the shaft (45), allowing the obstructing portion (43) to bend upon impact with a burst impeller fragment.
